Parts and Valves

Nederman MikroPul can provide all the accessories you need to operate any dust collection system we manufacture and help you choose the right accessories for your application. Our offerings include drum covers, valves / airlocks, hopper vibrators, leak detection kits, screw conveyors, and sonic horns.

PneumaFill™ Pneumatically Sealed Drum Covers

The patented PneumaFill™ Drum Cover uses a flexible pneumatic seal that conforms to dents, warping, and other irregularities caused by routine handling. The result is an airtight seal that insures the integrity and efficiency of the system.

Diaphragm Valves

Designed exclusively for the Mikro-Pulsaire® line of dust collectors, these valves are an essential part of the cleaning mechanism. Manufactured to rigid specifications, these are available in the following pipe sizes: ¾”, 1”, 1 1/4”, 1 ½”. Repair kits for all size diaphragm valves are also available from stock.

Solenoid Valves

Fast opening, long life, and high flow are the hallmarks of these valves. Ruggedly constructed of brass, Nederman MikroPul solenoid valves do not require a minimum operating pressure. All valves are two-way direct acting, and work on a normally opened or closed mode. These are available in ¼” or 3/8” NPT.

Rotary Valves

The Mikro-Airlock™ is a rotary valve consisting of a cylindrical housing, a vaned rotor, and (in most cases) a drive. The rotor fits snugly into the precision machined housing, thus minimizing air or gas leakage while effectively feeding or discharging the material. The material to be moved enters the Mikro-Airlock by gravity. As the vanes rotate, appropriate quantities of material are delivered to storage or to process.


Various designs are readily available from our large inventory including side removal and top removal – three designs: one piece venturi / retainer assembly for snap-ring bags, clampless design allowing removal of bag and retainer as a unit, twist lock design with separate venturi and retainer for fold-over bags

Leak Detection Kit 

The MikroPul leak detection kit uses an ultraviolet light source and a non-hazardous fluorescent tracer compound to reveal process air leaks quickly, reliably, and safely. Introduced into the process gas stream. The tracer compound visually shows filter bag tears, holes, tubesheet leaks, and structural leaks between the clean and product sides. Each kit includes a leak detector light, carrying case, battery pack, shoulder strap, spare bulb, UV absorbing glasses, and fluorescent tracer compound.
